# Item-Level Trial Scope Map

Separate a trial add-on from other subscription items that remain billable.

## Scope
Preparation and review only. No account action or professional decision.

## Inputs
Subscription/item IDs, billing mode, trial offers, recurring prices and invoice preview.

## Workflow
1. Inventory trial scope at subscription versus individual item level.
2. Keep non-trial items and their charges visible.
3. Check flexible billing-mode evidence and documented feature eligibility.
4. Return a review map without configuring offers or charging.

## Output contract
item | trial_offer | billing_mode | trial_scope | normal_charge | invoice_evidence | hold

## Fictional acceptance test
Fictional add-on A has trial offer while base B costs 20. Trial A does not make B free. Missing billing-mode evidence holds compatibility; no invoice or charge is created.

## Review gates
Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
